Knives, scissors and other prohibited items that were confiscated at the airport during security checks by Transportation Security Administration screeners are on display prior to a news conference at Los Angeles International Airport in this August 29, 2003 file photograph. The Transportation Security Administration said on March 5, 2013 that travelers can soon bring small pocket knives on board airplanes for the first time since the September 11 attacks, sparking outrage from flight attendants who said the decision would endanger passengers and crew.
